Effects of Process Parameters on Sheets Warp of Clinching Based on Abaqus

Due to significant advantage, clinching is applied extensively in the automobile. In the clinch experiment, the sheets out of clinch joint has obvious warp. According to the theory of plastic deformation, as the pressure of the binder, the area of the binder and the friction factor have higher degrees, the warp of the sheets has lower degree. Abaqus was used to numerically simulate the clinch process and verify the result.
